Abstract

A connection device for the connection of cannulas, catheters, flexible tubes or the like comprises two connecting parts provided with connecting nozzles or flexible tubes which each have an outer and an inner cone for the non-positive connection thereof. In order to protect the connecting parts against contamination by contact with hands or nonsterile articles before joining, during connection and after production of the connection and in order to ensure that the connecting part located adjacent to the patient closes automatically after unintentional release of the connection, the inner wall of the passage channel of the connecting part provided with the inner cone is provided with a radially extending groove in which there is mounted a valve disc which shuts off the passage channel and is made of an elastomeric material with a central slot. The connecting part with the outer cone is connected to a protective sleeve surrounding it concentrically, the inner diameter of the sleeve being larger than the outer diameter of the part provided with the inner cone. An annular space which is deeper than the insertion length of the inner cone is formed between the protective sleeve and the pipe piece provided with the outer cone. In its coupled state pushed into the inner cone, the outer cone passes through the valve disc with at least partial exposure of the slot. <IMAGE>
